A nurse is providing teaching to a client following surgery to repair a detached retina of the left eye. Which of the following instructions should the nurse include in the teaching?

Choice A reason: Advancing the walker and taking a step towards it is the correct technique, ensuring stability by moving the walker first, then stepping. This maintains balance and prevents falls, aligning with safe walker use protocols, so no intervention is needed for this action.
Choice B reason: Taking multiple steps while holding the walker compromises stability, as the walker must be repositioned after each step to ensure support. This increases fall risk, requiring the charge nurse to intervene to correct the technique and ensure the client’s safety during ambulation.
Choice C reason: Grasping the walker by the hand grips on the upper bars is correct, as it provides optimal control and balance. This standard technique supports safe mobility, and no intervention is required, as it adheres to proper walker use guidelines.
Choice D reason: Lifting the walker as it is moved forward is acceptable for lightweight or rolling walkers, depending on the client’s strength and model. While sliding is preferred for standard walkers, lifting is not inherently unsafe, so intervention is unnecessary unless improper execution is observed.

Choice A reason: Frequent nosebleeds are not linked to coarctation of the aorta, a congenital aortic narrowing. They may result from hypertension or nasal issues, but coarctation causes differential blood pressure, with high upper body pressure, not nasal vasculature changes, making this an unrelated finding.
Choice B reason: Weak femoral pulses are expected in coarctation of the aorta, as the narrowing restricts blood flow to the lower extremities. This creates a pressure gradient, with stronger upper body pulses, detectable in infants, guiding diagnosis and management of this cardiovascular defect.
Choice C reason: Increased intracranial pressure is not associated with coarctation, which affects cardiovascular dynamics, not cranial pressure. It may occur in neurological conditions, but coarctation’s primary effect is hypertension above the narrowing, not brain-related changes, making this an irrelevant finding in this context.
Choice D reason: Upper extremity hypotension is incorrect, as coarctation causes hypertension in the upper extremities due to restricted aortic flow. Blood pressure is higher above the narrowing, with strong brachial pulses, while lower extremities experience reduced flow, opposite to hypotension in the upper body.
